Does anyone have how to translate this solar stuff - Page 7

Well . Inverters,racking and all have made it . Only thing i am waiting on now is the panels . And the wood . Will be bracing my shop up a bit more so i can make it sturdy. Have a buddy that is much better at doing that type stuff than i am.
Have 1 whole rail up. The rest have to wait until i can get the sheeting to go under the tin so i can evenly space my railing to 32inches apart. The guys who built this had to do it cheap. And i have to pay the price now for it.

Got few rails up. Waitin on more l feet though so I can get more in. Got a big gap in middle to be able to get em up out my way
Rafters are almost at a angle . Made it a pain to get a stud. And the bottom. There over on the side a bit . Thankfully they was easy to see just lean over and look.

Looks good to me! Keep up the persistent, diligent work on this project, because the payoff is worth the effort.

Im looking . I am trying to decide if i am going to run ac from inverter to the house . Or mount the inverter on the house and run the dc to the house . Cable run is around 115 ft to meter from the shop. Trying to decide what will be the most efficient in the long run.

Ac has less amps to push and less volt drop / line loss so its best to run ac line imo as its going to a inverter regardless. It also depends wheres the best place is to keep the inverter out of the elements

Incorrect. It's voltage that determines the efficiency.

Unless the latest inverters are silent, I'd put it anywhere other than the house. The 60Hz humm that I have heard most large inverters producing is something I am glad I don't have to listen to in my garage or attached to my house.

I was under the impression being it was 350 volts of dc it may have a little less drop . It would be less of a voltage drop to the house than 240 volts ac . But also seem to remember tesla and edison ac being more efficient to transfer . I figured i would throw that out by someone who is smarter than i am.

. Am going to use 8 guage wire from the shop to the house though . Measured today . From the shop where i was going to mount inverter on shop is 112ft. give or take a couple inches for disconnect box.

Good point. Its on the opposit side of where i would sleep . But. It would be right on the side of my little boys room.

How many amps are you going to be running through that wire? Have you looked distant and amp charts?
You need to be careful about voltage rise. The inverter will increase the voltage to feed it back to the grid. If you have too much voltage rise from using wire not suited for that distance it will just shut down the inverter.

Here this explains some on voltage drop and why it is important
